Section 4. Running the CMWS Model Application
4.1 Manual Execution
if uploading to a remote host then execute the following
cmws_model_run remote [remotedir] [remotehost] [username] [password]
if copying to a local directory
cmws_model_run local [localdir]
4.2 Automated Execution
Interval depends on Hardware CPU Speed and RAM.
Consider upload time if transfering generated files to a remote host.
Server: http://www.agtucast.com
Hardware: AMD CPU @ 1.7MHZ with 1GB RAM, Fedora Core 7
Software: MySQL - MySQLdb API, Python
Performance: CMWS Location takes ~20 seconds.
100 locations will take about 20 minutes, would execute once per hour.
